"I realised my friend had been killed. There were bits of his body, his body armoury and kit strewn across the field. There was a child who had his toes blown off from the blast that had began running away at that point." — Combat First Aider, Afghanistan (name omitted)

"She appeared to have been doused with petrol, set alight and shot in the head … Fused to her was the baby she must have been holding at the time of the execution. I see this woman and child whilst sleeping … I feel ashamed I was not there fast enough to stop what happened." — Serviceman, East Timor peacekeeping mission

Recommendation for annual mental health screening

The Senate committee report's top recommendation was that every single ADF member must undergo annual screening for mental illness in order pick up on problems and mitigate the stigma of "seeking out" help.

As one veteran explained to the inquiry: "As soon as you are injured you are like a dog — you are kicked out of the pack and there is no way of getting back into that pack."

"We didn't accept people with psychological conditions very well, we didn't treat them very well, and unfortunately I was also one of those people that didn't treat people with respect … through no fault of my own; that was how I was trained," he said.

Senator Anne McEwen was on the committee and said the inquiry focussed on what Defence and the Department of Veteran Affairs could do to address the ongoing problems.

"It's not good enough for the people who go and fight to protect our country to not receive attention for their mental health issues," Senator MacEwen said.

Calls for a national identification number for all members

For Mr Kasmarek, his saving grace was one-on-one support from an RSL officer and veteran advocate, Mark Keynes.

"Mark pretty much picked me up out of the gutter, got me the help, the support, and basically set me up to get where I am now," Mr Kasmarek said.

"It's hard to even put into terms and think about where I was two years ago compared to where I am now."

Mr Keynes himself experienced mental health issues but believes he was treated differently by Defence because of his rank as a Major.

"I was eventually diagnosed with depression; I put my hand up for help when I thought things weren't going well and I received help immediately," Mr Keynes said.

He believes mental health issues in the Defence Force are fuelled by a "harden up" mentality.

"Our forefathers just suffered in silence," he said. "The horrific stories that must have come back from WWI and WWII, they just drank themselves into oblivion, and too many one-way trips to the woodshed. And we still have people doing that now."

Mr Keynes added a national identification number for all members would help streamline the process, and was a recommendation also made by the Senate committee.
